The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments.

An aspect of the utility model provides an oil pan, including oil pan body 1 and total oil duct 2, total oil duct 2 is located in oil pan body 1 and including first oil duct 21, the both ends of first oil duct 21 are provided with first oil-out 211 and second oil-out 212 that are used for with oil pump connection respectively.

Through set up first oil duct 21 in oil pan body 1, the both ends of first oil duct 21 set up first oil-out 211 and second oil-out 212 respectively, according to the needs of difference, through the orientation of adjustment oil pan, one among oil pump ability and first oil-out 211 and the second oil-out 212 intercommunication, thus, an oil pan just can satisfy the engine of same platform in the demand of arranging of different whole cars, when having solved same platform engine and being applied to different whole cars and arranging, need the problem of redesign oil pan, and the too many problems that cause oil pan lectotype mistake and assembly error of oil pan kind.

The shape of the first oil passage 21 depends on the specific situation of the engine, and the first oil passage 21 in fig. 1 is only one specific embodiment thereof.

Because the level of the lubricating oil in the oil pan directly affects the performance of the engine, the lubricating oil is too low to be beneficial to the lubrication of all parts of the engine; too high a lubricant level will again affect the efficiency of the engine and also tend to allow oil to enter the combustion chambers of the engine. In order to achieve a desired depth of lubricating oil under a certain condition of lubricating oil and facilitate engine operation, preferably, the oil pan body 1 comprises a shallow groove area 11 and a deep groove area 12; the first oil passage 21 is arranged in a first direction from the shallow groove region 11 to the deep groove region 12. The deep groove region 12 is mainly used for storing lubricating oil flowing back from each friction pair and the inner surface of the engine, and the shallow groove region 11 and the deep groove region 12 are provided in the oil pan in order to make the depth of the lubricating oil reach an ideal state under the condition that the lubricating oil is constant.

Wherein, the assembling surfaces of the shallow groove region 11 and the deep groove region 12 are arranged on the same plane; the transition area with the inclined bottom plate can be arranged between the shallow groove area 11 and the deep groove area 12, so that the transition between the shallow groove area 11 and the deep groove area 12 is smooth, and oil stains are prevented from being accumulated.

When the oil pump is installed, the oil inlet of the oil pump is communicated with one of the first oil outlet 211 and the second oil outlet 212 on the oil pan, and the other one of the first oil outlet 211 and the second oil outlet 212 is blocked by the cylinder block of the engine.

preferably, the first oil outlet 211 is opened on the first end wall 111 of the shallow groove area 11, and the second oil outlet 212 is opened on the second end wall 121 of the deep groove area 12. By the arrangement, the oil inlet of the oil pump is communicated with one of the first oil outlet 211 and the second oil outlet 212, and the other of the first oil outlet 211 and the second oil outlet 212 is blocked by the cylinder block of the engine.

In order to facilitate the oil pump to suck oil, preferably, the main oil passage 2 further includes a second oil passage 22, the second oil passage 22 is fixedly connected to the first oil passage 21, and an oil suction opening is formed in an end of the second oil passage 22 away from the first oil passage 21. The oil suction opening is not shown in the drawing, but is blocked by the side wall of the oil pan. The second oil passage 22 is communicated with the first oil passage 21, and the second oil passage 22 may be arranged in a vertical direction or in an included angle with a horizontal direction.

Preferably, the second oil channel 22 is located in the deep groove region 12, and a distance is reserved between the oil suction opening and a bottom plate of the deep groove region 12. Thus, the lubricating oil pump is beneficial to sucking lubricating oil.

When the lubricating oil is used for a period of time and needs to be replaced with new lubricating oil, the oil pan body 1 preferably includes an oil drain hole 3, and the oil drain hole 3 is provided in the side wall of the deep groove region 12. Thus, the old lubricating oil can be discharged without disassembling the oil pan, and the new lubricating oil can be replaced. The oil drain hole 3 is arranged on the side wall of the deep groove area 12 instead of the bottom plate, so that the oil leakage event caused by loosening of screws of the oil drain hole due to bottom contact of a vehicle in the process of running on an uneven road condition can be avoided.

When the oil pan is connected with the cylinder block of the engine, various connection modes can be adopted, preferably, the oil pan body 1 comprises a flange for connecting the oil pan body 1 with the engine cylinder block, and a through hole 14 for a fastening assembly to pass through is arranged on the flange. In the oil pan of the embodiment shown in fig. 1, the fastening assembly is a bolt assembly by which the oil pan and the engine block are fixed together. When the oil pan needs different orientations, only the orientation of the oil pan needs to be adjusted, and then the oil pan and the cylinder block are fixed through the bolt assemblies.

In order to prevent dirt from entering the lubrication system, it is preferable that a filter screen is installed in the oil passage 2. The filter screen can set up in the inside of oil duct 2, also can set up in the oil sucking mouth department of oil duct 2, in a word, as long as reach the purpose that filters lubricating oil and avoid filth portion to get into lubricating system.

The oil pan further comprises an oil cup through which lubricating oil can be added when the lubricating oil becomes less.

A second aspect of the present invention provides an engine, the engine includes a cylinder body provided with an oil pump and an oil pan, wherein the cylinder body is disposed on the oil pan, the oil pump communicates with one of a first oil outlet 211 and a second oil outlet 212, and the other of the first oil outlet 211 and the second oil outlet 212 is blocked by the cylinder body. The position of the oil pump in the engine is fixed, as shown in fig. 2, when one end of the oil pan, which is required to be provided with the shallow groove area 11, is located right below the oil pump, the first oil outlet 211 is connected with an oil suction port of the oil pump, and the second oil outlet 212 is blocked by the cylinder body and can not discharge oil; as shown in fig. 3, when one end of the oil pan, which is required to be provided with the deep groove region 12, is located right below the oil pump, the second oil outlet 212 is connected to an oil suction port of the oil pump, and the first oil outlet 211 is blocked by the cylinder body and cannot discharge oil.

The engine and the vehicle are provided with the oil pan, the technical advantages are the same as those of the oil pan, and the description is omitted.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. The utility model discloses an in the technical conception scope, can be right the utility model discloses a technical scheme carries out multiple simple variant, for example, first oil duct 21 and second oil duct 22 can set up to an organic whole, also can set up to two independent oil ducts that have oil absorption opening and oil-out respectively. Including the various specific technical features, may be combined in any suitable manner, for example, the first oil passage 21 may be changed to a different shape, curved or straight, depending on the engine, and the oil passage cross-section may be circular or polygonal.
